New server threads, just like nerf threads, are a common everyday occurrence in the World of Warcraft forums. Well, a poster named Scarecrow asked whether it is true that two new servers will come up today. Apparently, an unnamed Blizzard (blue) poster hinted about this but the original thread was deleted. MVP (Most Valuable Poster) Palehoof replies with an example convo between those asking for new servers and blue posters:

Blue: We regret that we cannot provide any information about new servers at this time. We will announce new servers as soon as we are able. Please stop asking, as this answer will not change, and the question has become spam.

Player: We don't want an ETA or anything, just tell us when it might be!

After the Blizzard poster stops responding the general posts that follow is: Why are you ignoring us? If you'd just answer we’d stop asking.

Then Blue posters stop replying completely. Palehoof concludes with, "When they can tell us, they will do so, and you won't need to ask. Until they can tell us, they will not, and you may as well not." Hmm. Why are people asking for new servers/realms anyway when there are other recommended servers still available? First reason perhaps are world firsts, like the Gates of Ahn'Qiraj for example. Or they want it so they can reroll a new character in a server that's not already swimming in level capped characters.

Anyway, Blizzard guy Tseric stepped in after five pages of argument and said exactly what Palehoof said. "We will announce new realms upon their arrival, as per usual. Please note that a thread on this topic is made every day. I say that with no hyperbole."
